Roch Guérin

Roch Guérin is a French computer scientist. He is the Harold B. & Adelaide G. Welge Professor of Computer Science at the McKelvey School of Engineering at Washington University in St. Louis, and chair of the Computer Science & Engineering department at that university. Prior to that he was the Alfred Fitler Moore Professor of Telecommunications Networks and professor of electrical and systems engineering and computer and information science at the University of Pennsylvania. He worked for 12 years at the IBM Thomas J. Watson Research Center.

Obtaining his BS from École nationale supérieure des telecommunications, he received his MS in 1984 and PhD in 1986 from the California Institute of Technology.
